Application filed June 26, 1923.

T 0 all whom it may concern:

Be it known that I, E wane P. na, a citizen of the United States,residing in South Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvement in of which.the following is a spec My invention relates to bags, for cement andsimilar materials, which are made of a textile fabric and are closed bygathering their open upper ends and tying them with cord or wire.

Cement is now almost universally put upon the market and handled in bagsof heavy closely-woven cotton and the bags, because of their high costrelative to the value of the cement, are collected when emptied andrefilled as many times as possible. And since it is impractica le toclose bags so used by sewing up their open ends, is usually done in thecase of bags which are used once only, it has long been the standardpractice to tie up the upper ends of the bags, which, to prevent theties from slipping off, are turned in around the edge and sewed down toform a half-inch hem, the empty bags being first tied up and then filledthrough a self-closing valved opening formed for the purpose at one ofthe lower corners in the making of the bags. The means thus provided forretaining the tie in place are objectionable not only because the extrahalf inch or so of cloth and the thread required and the expense offorming the hem add materially to the original cost of the bag but alsobecause the stitches soon breal: or pull out and the hem frequentlyceases to function long before the bag itself is worn out. It hasrecently been proposed to omit the hem and merely to sew with heavythread a line of stitches around the upper end of the bag, the extrathickness thus provided serving to prevent the displacement of the tie;but this practice, while saving the additional material required for thehem, is open to the other objections noted.

My present invention consists in incorporating in the body of the fabricfrom which the bags are made a larger or heavier thread, or threads,which, when the bags are made up, will extend around each, at or closeto its upper se s, and so serve like the hem or line of stitches as aretainer for Serial No. 647,?95.

the tie. This relatively heavy thread is usually introduced as a warpthread, the outer thread or any one of the half dozen or so threads atone edge of the web, since it is usual to so out a web of cloth and foldand sew the bag lengths as to leave one of the selvage edges at theupper open end of the bag.

The invention is illustrated in the accompanying drawing, showing inFig. 1 a side view of an entire bag embodying my improvement and in Fig.2 an enlarged detail of a portion of the upper end of the bag, wherein(4 indicates the fabric of which the bag is made and Z) the heavierthread woven therein.

The bag in question is made up from a suitable length out from a web ofcloth, of the width required for the length or depth of the bag, whichis woven in the usual manner but with the larger warp thread or cord a,or with two or more of such threads, at one of its selvage edges. Eachbag length, is customary, is first folded transversely along its medianline, the fold forming one side of the bag and with the corded edge atthe top, and the folded piece is then sewed with a row of stitches whichis run from top to bottom, oining the two ends of the piece and soforming the other side of the bag, and thence across the lower end toclose the bottom of the Finally, the sewed is turned, to turn. in theedges of the cloth. The method of forming the self closing valvedopening for filling the bag, by turning back the low er corner of doublematerial adjacent the folded side before stitching the bottom of thebag, is known and need not be further described.

This h .avy thread is equally ellicient as the hem, or the row ofstitches, heretofore used for retaining the tie in place and, inaddition, adds little if anything to the cost of the woven fabric andwill wear and retain its eiiiciency as long as the bags can be used.

What I claim as new, and desire to secure by Letters Patent, is

1. A bag of textile material for cement and the like having for itsupper open end a selvage edge of the fabric in which is woven a warpthread or threads of relatively large size.

2. A bag for cement and the like which is made up of a folded and sewedlength of textile fabric having woven in one of its selvage edges a Warpthread or threads of relatively large size and in which such cordedselvage edge forms the upper open end of the him.

3. A cotton or similar textile fabric for the manufacture of bags forcement and the like which has Woven in one of its selvage edges a Warpthread or threads of relatively large size, such corded edge to form theupper open ends of the bags made up from lengths cut there-from.
